Significant effect of alkyl chain length on fluorescent thermochromism of 9,10-bis(p-alkoxystyryl) anthracenes

摘要

9,10-Bis(p-alkoxystyryl) anthracenes (DSA-pn(n)) with different length of alkyl chains (n = 4, 8, 16) were synthesized. It was found that they exhibit aggregation-induced emission (AIE) properties and significant fluorescent thermochromism. Besides, the thermochromic behaviours of DSA-pn(n) show great dependence on the length of alkyl chains.
